Talked to Ron for about a minute and he was very rude. I was trying to find out how much it would be to replace filters he said 169 but i need to change it to 179. I had no problem with that. Then i told him if i get 2, then it will be double? and he raised his voice and told me thats not what he said. Then he proceeded to tell me it would be double. I then told him isnt that what i just said? Then got angry and told me not to put words in his mouth. Terrible customer service do not recommend.
